[0141] Conveyor belt adjusting part 85: Adjust the tension of the first conveyor belt 81.

[0142] Working principle: The raw material (plastic film) is fixed on the unwind shaft air shaft mechanism 105. The unwind shaft air shaft mechanism 105 rotates to convey the plastic film outwards. The unwind shaft deviation rectifying frame 104 will adjust the tension of the plastic film and stably convey the plastic film to the side glue seat. The plastic film reaches the forming template guide wheel 68 through the side glue seat. When making plastic bags of different widths, different widths can be selected by directly using or reducing the number of forming template guide wheels 68. By adjusting the width of the forming template guide wheel 68, the plastic film will be transmitted to the template in a specific shape. The template is the key to determining the width of the bag, and the widths of the bags made with different templates are also different. The plastic film will be transmitted on the template, and the forming template pressure wheel 67 and the guide rod 66 will provide guiding assistance beside it. At the same time, the glue gun 72 will apply an appropriate amount of glue on the inner side before the two sides of the plastic film coincide. After the plastic film is merged along the guide on both sides, it will stick together to form the prototype of the plastic bag.

[0143] At this time, the plastic bag will enter the paper pulling wheel mechanism 6 through the paper pulling seat 60. After eliminating the static electricity of the plastic bag, the plastic bag will be smoothly transmitted into the paper tube guide plate mechanism 5. At this time, the plastic bag is transported on the paper tube guide plate 17, and the cutter shaft 15 rotates synchronously. Before the upper cutter on the cutter shaft 15 rotates to the position of cutting the plastic bag, it will pass through the static electricity removing brush roller 22 to remove the static electricity on the cutter 18. After the static electricity is eliminated, it will cooperate with the lower cutter 18 to cut the plastic bag. The length of each bag can be adjusted by adjusting the rotation speed of the cutter shaft 15. The conveying rubber wheel 21 will transport the cut plastic bags. By continuously changing the position of the conveying rubber wheel 21 through the conveying cam 14, the cam follower fixed rod 24 and the eccentric gear 19, a speed difference is generated between the conveying rubber wheel 21 and the plastic bag in transportation, resulting in a speed difference between the previous plastic bag and the next plastic bag, so that the plastic bags are spaced apart. The plastic bag is transmitted to the adjustable conveying wheel 32, and the adjustable conveying wheel 32 rotates at a different speed from the previous components, further increasing the spacing between the plastic bags.

[0144] At this time, the plastic bag is fed into the bottom-opening mechanism 4. The paper tube stripper 94 will smoothly send the plastic bag onto the large drum 35. The bottom-opening inserting knife inserts the plastic bag into the large drum clamp 37. The large drum clamp 37 will synchronously clamp the plastic bag. At a specific position, the bottom-opening suction cup will adsorb one end of the plastic bag, and the auxiliary bottom folding device 100 and the bottom-opening center guide plate 99 will open the bottom. At a specific position, the suction cup will release the plastic bag. The adsorption and release are controlled by the cam-actuated cylinder 46. The cam-actuated cylinder 46 can be adjusted by the drum linkage cam 44. When making bags of different specifications, the suitable bottom folding device 100 can be replaced. Both the bottom folding device 100 and the bottom-opening center guide plate 99 can be adjusted in position. After the bottom opening is completed, the bottom-opening conveyor wheel 96 will assist the large drum 35 in conveying the plastic bag. Then, the second conveyor belt 102 will continuously escort the plastic bag for transportation. The plastic bag will then be transmitted to the inserting knife mechanism 9. The inserting knife mechanism 9 will insert the bottom-opened plastic bag into the large drum clamp 37. Then, the plastic bag will be transmitted to the bottom-closing mechanism 12. The bottom-closing mechanism 12 moves synchronously with the large drum 35 and will close the bottom of the bottom-opened plastic bag. The distance between the gears of the bottom-closing mechanism 12 can be adjusted to adjust the bottom-closing time.

[0145] After the bottom is closed, the plastic bag will enter the dispensing drum mechanism 11. The dispensing drum mechanism 11 will adjust the tension of the second conveyor belt 102 to make the plastic bag better transmitted to the dispensing belt drum 77. The clamp of the belt drum 77 will clamp the plastic bag and rotate to the pasting position of the bag bottom patch unit 7 under the cooperation of the conveyor belt. The patch paper roll is slowly conveyed to the conveying mechanism in the feeding mechanism under the traction of the upper and lower paper pulling rollers driven by the servo motor in the patch paper pulling mechanism. There is a braking function in the feeding mechanism (the braking effect is generated by the friction between the braking belt and the braking wheel), which can prevent the feeding mechanism from continuously feeding. Moreover, there is a swing roller mechanism between the feeding mechanism and the patch paper pulling wheel mechanism 6. The swing roller mechanism is set for stable tension to prevent the patch paper pulling mechanism from suddenly accelerating or the feeding mechanism from suddenly decelerating. The swing roller will swing within a certain range under the gravity of itself and the weight of the swing roller mechanism to absorb the fluctuations caused by the sudden lengthening or shortening of the paper.

[0146] After the paper is pulled by the patch paper pulling wheel mechanism 6, it will be sent to the conveyor mechanism 3 after the bottom is opened. The conveyor mechanism 3 after the bottom is opened will catch the paper through the conveyor belt, and suck the paper on the conveyor belt through the vacuum box. The power shaft of the conveyor belt is connected to the servo motor in the patch paper pulling wheel mechanism 6 through the synchronous belt pulley, so as to obtain power to drive the conveyor belt. While the conveyor belt is driving, the paper can be stably sucked on the conveyor belt and driven together with the conveyor belt. At the same time, at this time, the patch gluing mechanism above the conveyor belt will evenly apply glue (hot melt glue or other adhesives) on the surface of the paper as required (the gluing length can be adjusted by controlling the gluing time). The conveyor belt will convey the paper to the patch vacuum mechanism of the bottom patch unit 7. The patch vacuum mechanism of the bottom patch unit 7 is connected to the patch cutting knife mechanism through the synchronous belt and the servo motor driving the synchronous belt pulley 39 to obtain power. The suction cup on the patch vacuum mechanism of the bottom patch unit 7 will firmly suck when the conveyor belt conveys the paper over.

[0147] At the same time, it rotates together with the patch cutting knife mechanism driven by the servo motor. When it rotates to a certain angle, the cutter on the patch cutting knife mechanism will form a scissor-like mechanism with the knife rest on the patch vacuum mechanism of the bottom patch unit 7, and cut the paper into the length patches we need (the length can be adjusted by the speed ratio between the servo motors). At the same time, at this time, the suction cup on the patch vacuum mechanism of the bottom patch unit 7 always sucks the cut patch and rotates to the drum of the bag-making machine receiving unit. At this time, the servo motor needs to transfer the patch to the bottom of the bag we need according to the position of the bag on the bag-making machine receiving unit. If the distance is too large, the position of the patch vacuum mechanism of the bottom patch unit and the drum of the bag-making machine receiving unit can be adjusted to a suitable position by adjusting the adjusting nut on the main frame of the patch unit. When it is attached to the appropriate position, the suction cup on the patch vacuum mechanism of the bottom patch unit will cut off the vacuum, so that the patch is firmly attached to the bottom of the bag under the action of the glue. After the patch is attached, the plastic bag will rotate along the distribution drum. At the position of the receiving table, through the movement of the cam, the distribution drum will release the distribution drum clamp, and the plastic bag will firmly fall on the receiving table 10.
